                             Chapter 1 Introduction

     This package of asynchronous communications tools for IBM (COM1 - COM4)
and Digiboard (intelligent communications hardware, up to 32 ports) hardware,
consists of library (.LIB) files for each memory model (SMALL, DATA, PROGRAM,
LARGE), and for both IBM and Digiboard hardware.  It also includes all of the
source files, header files (with prototypes) and MAKE files needed to generate
the various libraries.  Batch files are included for calling make with
appropriate flags for each supported compiler.

     A working knowledge of 'C' and operation of your compiler is assumed.

     The "shareware" version is configured for the TURBOC compiler in .LIB
format, and comes with the small memory model library only (ASYNCS.LIB).
Header files with module prototypes for the library routines are included, as
well as TEST.C for testing the modules on your system.  No other source code is
provided with the shareware version or support for Digiboard hardware.

     Also included are useful demonstration utilities as described in the
manual.

     Becoming a registered user will provide full source code to every module,
make files, support for other C compilers, 3 more utility programs, and a bound
laser printed manual.  There is also full support for Digiboard communications
boards which will allow up to 32 ports on your PC.  You will also be put on our
registered users list and receive upgrade notification whenever new, expanded
versions become available.

                             Chapter 2 Installation

2.1 Shareware Version

     The shareware version contains only the TURBOC small memory model library
(ASYNCS.LIB), include files (*.h), and DATAMON.EXE (a nifty data line monitor
program for debugging and testing RS-232 devices).  All files are compressed
together into ASYNC.ARC.

     First copy ASYNC.ARC to the subdirectory where your C source files are
kept.  Then type ARC E ASYNC (or PKXARC ASYNC if you have this fast uncompress
program) to uncompress the files.

     Copy ASYNCS.LIB to your \TURBOC\LIB subdirectory.

     Copy *.H files to \TURBOC\INCLUDE subdirectory.

     Print out the documentation for these tools (ASYNC.PRN).  README (this
file) can be printed by typing PRINT README.  ASYNC.PRN should be printed to an
IBM Graphics (EPSON) type dot matrix printer only.  Type:

     COPY /B ASYNC.PRN PRN:

     The shareware manual is approximately 35 pages long.

     Follow instructions in the manual to test your installation with a simple
communications test program (TEST.C).

3.1 Communications Hardware

     Please see Chapter 9 in manual for a complete description of products and
services available from Nordtech Research, Inc.

     One of the most useful tools available when developing communications
software is an RS-232 breakout box.  This device allows monitoring of data and
control (handshake) lines at the physical level, provides a means of rewiring
from one line on one side to another on the other side.  By connecting this
device in line with a serial cable, it becomes a science rather then an art to
establish communications between two devices.

     Please call for our latest pricing and availability on these and other
useful testing devices, cabling, modems, etc.  You can count on getting a
better price from us than the list price usually charged by communications
specialists.
